Schneider Electric NAL36800 Molded Case Circuit Breaker

Schneider Electric's NAL36800 is a three‑pole molded‑case circuit breaker rated for 800 A at 600 V, intended to protect feeders and distribution circuits in industrial and commercial panels. It is part of Square D's NA/NAL family and uses I‑Line plug‑in mounting for installation in compatible panelboards. The device employs a thermal‑magnetic trip mechanism to provide overload and short‑circuit protection, and it carries an interrupting rating of up to 50 kA at 480 VAC. This MCCB is suited for high‑current protection in compact form factors where reliable overcurrent protection is required in distribution systems; verify panel compatibility with I‑Line/NA style devices and ensure the installation voltage and fault‑current environment match the NAL36800's 600 V, 800 A, 3‑pole rating and its 50 kA interrupting capability at 480 V.
